It's a blue silkie hen who has had crooked beak her whole life and has been just fine. Shes almost a year old. I woke up this morning and went out to go let the birds out and somehow her bottom beak looked like it was missing I took a closer look and her beak isnt gone, it looks like her jaw broke and her beak is dangling. Shes eating and drinking and acting normal somehow. The only behavior change is shes shaking her head occasionally. I've never seen anything like this so I have no idea what to do. I need help, I dont know if I should put her down or if theres something I can do to save her. Its physically impossible for predators t ok get in the coop so it wasnt an attack.
